The brake system has several different signs that indicate its status and possible problems. These include:
1. An exclamation mark icon: This usually means there is a problem with the service brake system. This problem may involve low brake fluid, excessive brake pad wear or damaged sensors, and the sign will be activated once these problems are detected.
2. The "P" sign: This means that the parking brake is applied, that is, the handbrake is applied. If this sign does not light up when the handbrake is applied, it may indicate a problem with the system.
3. A circle with an exclamation mark in brackets: This is also a brake system warning sign. In some vehicles, it will light up briefly after the ignition switch is turned on, and then go out after the engine is started. In addition, this sign will light up when the handbrake is applied, the brake fluid level is too low, or there is a problem with the brake system.
4. Icons with brake light patterns or brake equipment graphics: These signs are designed to remind the driver to check or maintain the brake system, or to show the current status of the brake system.
In some areas, the brake system warning sign may be a triangle with a lightning bolt at the bottom to indicate that emergency treatment is required.
In terms of color, an orange sign may indicate normal status, but if it flashes, it may mean an abnormal situation; red signs are mostly used to indicate a fault.
Once the brake system fault light is on, the driver should stop the car immediately for inspection. The first step is to stop the car safely and check whether the amount of brake fluid is sufficient. If the brake fluid is found to be below the minimum scale, you can contact rescue personnel to bring brake fluid to assist. If the brake fluid level is normal, it may indicate that there is a mechanical fault in the brake system. In this case, the vehicle must not continue to drive, but should be parked in a safe place and contact a maintenance service station for inspection. It is worth noting that when the red brake warning light is on, the ABS warning light is usually activated at the same time, because a fault in the conventional brake system will affect the normal function of the ABS.
